Eigenfactor™ Metrics, comprising the Eigenfactor™ Score and Article Influence™ Score, use JCR citation data to assess the influence of a journal in relation to other journals. These metrics, based on five years of citation activity, consider not just the count of citations but the structure of the citation network. Eigenfactor Metrics are available only for JCR years 2007 and later.
